Thanks for posting the source, a lot of it is new but understandable to me so I'll probably end up trying to add a site when I feel like working on something.
One reason why I wanted it was because I thought some of it was broken, but it doesn't seem so now. What I think happened is that after using it on over 20k songs in a row I may have gotten myself banned from AZlyrics and DarkLyrics. AZlyrics.com would give me a "Connection closed by remote server" error while working perfectly fine with a proxy, and since about a week ago it works like normal again. DarkLyrics.com does load, but whenever I try to go to a lyrics pages it returns nothing and just shows a blank page, while again working fine behind a proxy. Unfortunately that one hasn't changed back to normal yet.
